بررسی‌های ساختاری و مغناطیسی نانوذرات پروسکایت LaMn1-xCoxO3 (0/1، 75/0، 5/0، 25/0، 0/0 = x)
In this work, the structural and magnetic properties of LaMn1-xCoxO3 (x = 0.00, 0.25, 0.50, 0.75, 1.00) are investigated. The structural characterization of compounds by X-ray powder diffraction is evidence for a rhombohedral structure (R -3c space group). Much less increase of the unit cell volume suggests that Co enters in lattice as Co+2 for x ≤ 0.5 while much more decrease of the unit cell ...

We investigated the structural, magnetic and electronic properties of NixCr1-x alloy in the range 0.125≤ x ≤0.875 by using FP-LAPW method to solve Kohn-Sham equations. In structural study, we calculated the formation energy, lattice parameter and bulk modulus for bcc and fcc structures within ferromagnetic, ferromagnetic and paramagnetic phases. Our results indicate that the system preference ...
متن کاملOPTICAL PROPERTIES OF CO-EVAPORATED THIN FILMS OF BINARY Bi 0-Te 0 AND Bi 0 -V 0 SYSTEMS
Thin films of binary Bi 0 -TeO and Bi 0 -V 0 systems were prepared by the thermal co-evaporation technique in a vacuum at room temperature. The optical absorption edge of these systems are studied in the wavelength of 200-800 nm using a PERKIN-ELMER uv/Vis spectrophotometer. It is found that the value of n=3/2 in the Davis-Mott equation is best fitted for the fundamental absorption edge f...

In this research, YBa2Cu3O7-d (0 < d < 1) nanocrystalite superconductor was prepared by mechanochemical alloying method. We synthesized YBa2Cu3O7-d via mixing the BaCO3, Y2O3, CuO powders and milling in SPEX 8000 for 5h with weight ratio of ball to powder 10:1 and steel balls of 11mm diameter, followed by heating for 4h at 850 ˚C. The superconductor phase formation process was completed with si...
متن کامل0 v 1 5 A ug 2 00 0 Are Rindler Quanta Real ?
Philosophical reflection on quantum field theory has tended to focus on how it revises our conception of what a particle is. However, there has been relatively little discussion of the threat to the " reality " of particles posed by the possibility of inequivalent quantizations of a classical field theory, i.e., inequivalent representations of the algebra of observables of the field in terms of...
